VULCANIZATION OF WATER-PROOF FABRICS.

SPECIFICATION forming part of Letters Patent No. 226,259, dated April 6, 1880.

Application filed February 16, 1880. Patented in England January 14, 1878.

" ments in the vulcanization of VVater-Proof Fabrics, for which I have obtained a patent in Great Britain, No. 166, January 14, 1878, and of which the following is a specification.

The said invention relates to improvements in effecting the vulcanization of the india-rubber contained upon or constituting an intermediate layer between the fabrics of which the water-proof materials are to be composed; and it consistsin subjecting such coating or layer of india-rubber to the action of the vapor of chloride of sulphur, in order that the indiarubber may thereby become vulcanized.

In carrying out the said invention the compound fabric, either in the piece or in the form of garments or other articles, is submitted to the action of the vapor of chloride of sulphur until the desired vulcanization has been effected.

One method by which this is effected is by inclosing the fabrics, garments, or articles in a closed vessel or chamber and admitting therein the vapor of chloride of sulphur. This process is particularly valuable for the vulcanization of made-up garments or made-up goods, as the joints or seams which have been attached together by means of indiarubber solutions are vulcanized at the same operation.

' In case the fabrics retain any of the acid from the vapors this 'may be neutralized by immersing the fabrics in a weak alkali or subjecting the same to the vapors ofan alkali, by preference ammonia.

I claim as my invention- The mode described of efiecting the vulcanization of fabrics containing an external or an intermediate layer of iudia-rubber by submitting the same, either in the piece or in the form of garments or articles, to the action of chloride of sulphur, substantially in the manner hereinbefore mentioned.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

WM. ABBOTT.
